This project entailed the design of a roundabout within an existing traffic calming feature of sidewalk pop-outs for the City of Vista. The intersection was located along a safe route to school, and parents expressed concern about high traffic speeds. The City determined to construct the roundabout to provide traffic calming along the street. KOA provided a horizontal layout and typical section for the roundabout. We evaluated design vehicle turning templates, assessment of design speeds for entering, circulating, and exiting vehicles, and prepared striping and signing plans as well.
